You can make a "button" in the launcher to translate the mod. For example, when a player logs in to the game, they can choose which translation (language) they want, click on it, and then they don't need to do it again. It's clear that not everything will be translated, but it's still an option.Regarding the interface in the game: Example: replacing certain DLLs, it gave a translation into Russian. Then the OP updated something and everything was gone
